Understanding Compostable PLA Cold Cups(https://www.shenglinpla.com/product/compostable-cold-cups/): PLA Material: Compostable PLA cold cups are made from Polylactic Acid, a biodegradable and renewable plant-based polymer derived from renewable resources such as corn starch or sugarcane. This material offers a sustainable alternative to traditional petroleum-based plastics. Cold Beverage Service: Compostable PLA cold cups are specifically designed for serving cold beverages such as juices, iced coffee, smoothies, and soft drinks. They maintain the desired temperature of the beverage while providing a durable and leak-resistant container.

Because viscose is plant-based and therefore renewable, it is widely seen as a more environmentally friendly and sustainable material than other synthetic fibres. But is this true, and what about poly-viscose? The answer is mixed. The polyester component of poly-viscose is clearly problematic, deriving from hydrocarbons, with all the implications for climate change that industry brings, plus the chemical impacts from its manufacture. In that it is similar to other artificial fibres. http://www.hdl-nonwoven.com/
